摘要
SBS改性沥青在使用过程中经受热、氧、光及交通荷载等因素耦合作用发生老化,路用性能随之衰变。基于国内外SBS改性沥青老化研究现状,从组分迁移、微观结构转变、性能变化等方面对SBS改性沥青老化行为进行分析,探索其老化机理及影响因素,并对老化SBS改性沥青的再生提出建议。
The degradation of road performance can be caused by the combined effects of heat,oxygen,light and traf- fic load in the using process of SBS modified asphalt. Based on the current research about the aging of SBS modified asphalt at home and abroad, the aging behavior of asphalt was analyzed in terms of component migration, microcosmic structure and performance variation to explore its aging mechanism and influencing factors. Some proposals were also provided for the regeneration of asphalt after aging.
